Griffin has been taking heat after she posed for a photo with a bloody fake head designed to look like President Donald Trump. The comedian has since apologized and removed the photo from her social media accounts.

The Knoxville News Sentinel says Lewis Country Store has posted controversial messages before. A message referencing the 2012 Benghazi attack led to Shell Oil cutting ties with the store in October.

Because the sign is on private property and is not encroaching the public right-of-way, the convenience store owner is likely within their First Amendment rights to post such a message, a lawyer told the News Sentinel.
